Answer:
Radio waves and microwaves is the answer.
Explanation:
any wave having low frequency or high wavelength will have low energy.
For this case we have that by definition, the potential energy of an object is given by:
Where,
- <em>m: mass of the object
</em>
- <em>g: acceleration of gravity
</em>
- <em>h: height of the object
</em>
Substituting values we have:
Answer:
Relative to the ground its potential energy is:
Answer:
Under normal conditions – closed circuit – these contacts are touching each other, allowing the flow of electric current. These moving contacts are held together thanks to mechanical pressure exerted by another mechanism – a spring or compressed air
